Answer:
B.Plants
Explanation:
They are considered as autotrophs because they manufacture their own food and have the highest amount of energy.
Answer:
Homeostasis
Explanation:
Homeostasis is a mechanism of the body which involves negative feedback loops that helps the body to maintain a stable internal environment when there is an external or internal change.
An example of homeostasis in the human body is the regulation of the internal temperature of the body. When there is a change in the normal body temperature, for example, if your temperature drops sharply below 37 degrees Celsius, homeostasis kicks off in the body to maintain the normal body temperature. Homeostasis uses thermoregulation mechanism which triggers shivering to raise the body temperature in an attempt to return it back to normal.
Homeostasis also makes it possible for the body to maintain the balance of water and other substances in the body like calcium in our body. For example, when the calcium level drops below normal level, the parathyroid gland secretes hormone which helps in the increasing of blood calcium levels.
Homeostasis s a essential mechanism that helps keeps the body in a balance and functional state.
HIV is a retrovirus which contains RNA as its genetic material. Once HIV enters the body, it attaches to T cells that help other lymphocytes respond to infection. Gradually, HIV kills off most of the helper T cells. The RNA is inside the capsule of the virus and is labeled A.
That is correct. The type A, B, and O blood types refer to the glycoproteins on the red blood cell.
Answer:
Look below
Explanation:
Graph 1 does indeed show a sudden drop in fermentation (after the evolution of the first living cells). This change occurred because the evolution of the first living cells allowed them to perform a type of respiration unseen before -- aerobic respiration and non-fermentation forms of anaerobic respiration. In other words, they had a new way of making ATP/energy: steps like the Krebs cycle and oxidative phosphorylation. This change occurred because the amount of oxygen was increasing in the atmosphere, and organisms needed to find a way to adapt. It may relate to the increasing temperature because glycolysis doesn't release carbon dioxide whereas this new form of energy production did. If you have more gases in your atmosphere, you're going to see higher temperatures and global warming.
Graph 2: Label B represents the gas carbon dioxide. Label A showed the gases hydrogen sulfide and methane decreasing. This is because photosynthesis would take out such gases from the atmosphere. Label B shows the level of a gas increasing. It's carbon dioxide because photosynthetic organisms released a lotta oxygen which was toxic for most of them, and cellular respiration organisms evolved and in turn increased CO2 levels.
